Served in a tulip, solid black pour with a small collar of bubbles; minimal retention and lacing. In the nose, roasty malts, burnt bread, notes of dark fruits, wet wood, lacking any real bourbon qualities. Taste of dark malts, roasty and charred, light bourbon notes and neutral alcohol, with a lot of woodiness coming out, subtle dark fruits, and a weird moldy/astringent taste that turned into something like Play-Doh as it warmed. Medium body, slick mouthfeel, lower carbonation...left something to be desired. Strange that this didn't seem to work out so well, considering the base beer is really good. Usually a bourbon barrel doesn't detract from a beer, but that's what I felt happened here.
